Honestly, I find that as long as the DE keeps the "desktop" metaphor, it's not too difficult to jump ship. Windows 7 was the last version of Windows I used in anger, and I had no trouble switching to Cinnamon DE. Mate would've worked just fine, too. It's GNOME 3 and its ilk that I find frustrating, and keep having to apply tweaks to make it usable for me.<p>The couple of times I tried Plasma, I loved all the customisability of it; it's awesome that I can apply one theme and now it feels like Windows 7, or a different theme and now it's Unity. But the "default" feel of Plasma just feels overwhelming, and even though I could drill down into fifty levels of settings to get what I want, it still turned me off because what I really wanted was just better defaults...
